PHOENIX -- As fans streamed into Chase Field to see the Diamondbacks take on the Padres Friday night many were disappointed to hear one of the longtime voices of the team wouldn't be there.

Earlier in the day, the Diamondbacks announced color-commentator and former major league all-star Mark Grace was taking an indefinite leave of absence "to seek personal assistance."

Grace was arrested in Scottsdale Thursday night for driving under the influence. According to Sergeant Mark Clark, Grace was pulled over near 7200 McCormick Parkway for having an expired registration plate. Grace was allegedly drunk and driving without a court-mandated interlock device and with a suspended license.

This was Grace's second offense in 15 months.

"You know, I just feel sorry for him. We love Mark Grace, he's great and we just want to wish him the best," said fan Susan Reynolds.

One fan showed up to the game in a vintage Mark Grace jersey.

"It's a sad thing, he's a character, he's a good guy," said fan Murray Sharkey.

Others were less sympathetic, and said they felt let down by Grace's behavior.

"It is definitely a bad example. It's certainly not something you want your kids to look up to," said one fan. "I know a lot of the sports figures say, 'well I'm not here to be a role model,' but whether they like it or not, they are one."

Fan Adrienne Christy is giving Grace the benefit of the doubt.

"I've always like him and admired him. It's a heart breaker," Christy said. "We all have our failing and we can't be judging."
